Revision History ========================================================== ========================================================== Changes from 2.2.0 build 780 to 2.2.2 build 23: ========================================================== - Added warning message to warn that no SimulStream license is present if user tries to open 1 board in multiple capture/encoding sessions without SimulStream feature enabled. - Changed timeout-period in driver startup for checking whether a SimulStream evaluation key is enabled. - Fixed bug which could possibly crop incorrect vertical region if the user had enabled SimulStream capability but not CC decoding. - Fixed bug in CropApp and full-size PAL video can now be displayed in that application. - This driver now responds to MMAC_ADV_CONTROL2 and MMAC_ADV_CONTROL control messages. These affect controlling software de-interlace from an application written using the Osprey SDK. - Fixed bug where video driver crashed or behaved incorrectly when application requested HD video size (larger than 720x480 for NTSC). - Fixed minor video discoloration for every 4th pixel during de-interlacing when looking at RGB16 color format. - Fixed memory leak in audio portion of driver. - Provided registry-enabled workaround to turn off SimulStream warning message that displays when SimulStream is not enabled. To enable workaround, set HKEY_CURRENT_USER\Software\Osprey\Osprey100\Device0\VcDll\ExtFlags to 0x100. Changes from version 2.0.0 build 252 to 2.2.0 build 780: ========================================================== - A new feature available in this release of the Osprey MultiMedia driver is a free 10-day test drive of the Osprey SimulStream(TM) feature. Included in this release is a 10-day evaluation license for SimulStream. There is a user option to toggle this capability on and off. While in evaluation mode a watermark will appear on the active video region which denotes usage of an evaluation version of Osprey SimulStream (TM). After the 10-day trial period has expired, one may renew the Osprey SimulStream (TM) evaluation by visiting our website at http://www.ospreyoffers.com/ospreysseval. - A new feature, software de-interlace, has been added to the 'Advanced Features' page of the Osprey's video control dialog. De-interlacing is optimized for Windows 2000 and later; it will consume fractionally more CPU cycles when enabled under Windows NT. Please see Chapter 5 of the Osprey MultiMedia User's Guide for a description of de-interlacing. - The Closed Caption checkbox is now disabled when the Video Standard in use is PAL format, since PAL does not support closed captions. - Added warning message to warn that no SimulStream license is present if user tries to open 1 board in multiple capture/encoding sessions without SimulStream feature enabled. - Audio upsampling quality has been improved. - Fixed potential audio capture failure to start problem. - Fixed a bug in resuming from power-down state. - Fixed a bug which could potentially cause a Blue Screen crash when an application using the Osprey card terminated abnormally. - Fixed a bug which could result in a race condition when using SimulStream feature. - Fixed NetMeeting audio tuning wizard error message "Your soundcard does not support a microphone volume control". - Fixed microphone check problem in Powerpoint. When setting up an online broadcast presentation in Powerpoint, the error message "Powerpoint is not receiving sound from the microphone" has been resolved. - To make audio and video device driver names more consistent, a hyphen was added to the name of the Osprey audio device. For example, previous names were of the form "Osprey 200 Audio", and are now "Osprey-200 Audio". This may cause a problem with saved encoding profiles that have stored the old audio driver name. Applications such as the Windows Media Encoder, when loading a saved profile with this old name format, will issue an error and indicate that a device has not been found. The solution is edit the profile and change the audio device name. - Fixed memory access violation in driver. - The functionality of the parameter 'Progressive scan digital camera' has been renamed to 'Field Order'. The feature has been moved to the 'Advanced Features' page of the Osprey's video control dialog. - A bug which caused audio failure on some machines where Device Properties address of PCI device was 0, has been fixed. Changes from version 1.55 to 2.0.0: ============================================= - Versions 2.0.0 and later are capable of SimulStreaming. - The parameter 'Progressive scan digital camera' on the Video Source dialog page allows the user to select the scan order the driver uses, in order to accommodate a wider variety of cameras. This parameter allows to user to choose between even/odd and odd/even orders. - The parameter 'Access to Multiple Boards' on the Video Configuration page has been changed to 'Multiple Opens'. The meaning of this checkbox has also been changed. This checkbox should be selected when using the SimulStreaming feature of the driver. - Closed Caption decoding may stop after 8 hours when multiple streams are using the same Osprey card (i.e. when SimulStreaming). - The 'Apply to all boards' checkbox on the Closed Caption dialog page has no effect. Known issues in version 2.2.2: ========================================================== ========================================================== - With the existing SimulStream architecture, you MUST pair your fastest desired framerate with your session with the largest pixel size resolution when creating multiple capturing/ encoding sessions using the optional SimulStream feature. This is explained in the SimulStreaming_Users_Guide.pdf as "...all frames must be scaled copy or none of the frames must be scaled copy." If you do not follow this guideline, some streams may fail to start encoding/capturing, or a blue screen crash could possibly occur. - RealSystem Producer 8.5 / Heavy Load Problem: There is a known problem with RealSystem Producer 8.5/8.51 in which it adds video buffers to the capture device before RealSystem Producer has finished processing the buffers. Typically under non-loaded CPU utilizations this is not a problem because the buffer can be processed by RealSystem Producer before being prepared for capture. However, under heavy CPU load, the capture driver can prepare the buffer for capture before RealSystem Producer finishes or even starts processing the buffer. The result is typically a processed image that has a multicolored pattern in the image. The size / height of this pattern depends on how far RealSystem Producer has processed the buffer before it is prepared for capture. If you find this situation occurs first try to reduce your CPU load before contacting Osprey support. - PCI bus numbers of 16 or higher The drivers will fail to function properly with cards on PCI bus number 16 or higher. DirectXMedia: ========================================================== ========================================================== DXMedia version 6.0 works with DirectX version 3.0 for Windows NT. The DXMedia package MUST be installed in order for Microsoft Windows Media Encoder versions 7.0 and later, and AmCap, to function properly. It is provided on the CD. See the Installation chapter of the Users' Guide for instructions about installing it. Osprey-100/101/200/210/220 Windows NT Installation: ========================================================== ========================================================== During the course of this installation, you will be prompted to select from amongst three setup types: "Osprey-100", "Osprey-200/210/220" or "Custom". Select the: 1. "Osprey-100" setup type, if you are installing any combinations of Osprey-100 cards and/or Osprey-101 cards, only. If one of the cards you are installing is an Osprey-200, select one of the other setup types. 2. "Osprey-200/210/220" setup type, if you are installing any combinations of Osprey-100 cards, Osprey-101 cards, Osprey-210, Osprey-220, and/or Osprey-200 cards. 3. "Custom" setup type if you want more control over the installation. You will be prompted to select which components that you want to install. Important Notice ========================================================== ========================================================== If you are using an Osprey-500 or Osprey-2000 card in the same machine as your Osprey MultiMedia card, we strongly recommend that you upgrade the Osprey-500 or Osprey-2000 card to the version 2.1.0 or later driver.
